6816533 Blade Cylinder Seal Kit — Product Overview

The 6816533 Blade Cylinder Seal Kit is a versatile aftermarket replacement covering Bobcat X-331, 337G, 337WG, 341G, and 435 excavators. Designed for the blade cylinder with 1-3/4″ rod and 3-1/4″ bore dimensions, this kit matches OEM cylinder specifications 6815923 and 6815953.

The blade (dozer) cylinder on these mid-to-large Bobcat excavators performs dual functions: raising and lowering the front blade for site preparation and backfilling, and stabilizing the machine during heavy digging by transferring weight to the front blade. On the 341G and 435 platforms, seal failure under stabilization load results in blade creep, loss of machine stability during deep excavation, and external oil leakage.

The 6816533 kit uses polyurethane rod seals engineered for sustained holding pressure and NBR static seals etc for reliable containment. DJF Seals supplies this kit at factory-direct wholesale pricing — one kit supporting 5 Bobcat models across the X-331, 337, 341, and 435 platforms.
